Granite Powder Influence on the Static Mechanical Properties of Tapsi fiber-reinforced Hybrid Composites: A Comparative Study

ABSTRACT

Strength, weight, stiffness, environmental friendliness, and ease of manufacture are the key considerations for the selection of materials for today’s engineering applications. In this study, the hybrid composite was developed by reinforcing the alkali-treated tapsi fiber and micro granite filler into a polyester matrix using the hand lay-up method. Tapsi fiber is inexpensive, available in abundance, and the necessary amount of fiber needs to be prepared with minimal effort. Micro granite powder is one of the unused industrial wastes produced by the granite industry. Five different hybrid composite samples were created by keeping the tapsi fiber content constant at 20 wt.% and altering the micro granite powder content in polyester resin from 0 wt.% to 20 wt.%. Mechanical properties such as tensile, flexural, and impact strengths were evaluated to assess the hybrid composite’s load-bearing capabilities. Other characterizations such as FTIR and SEM are conducted to verify the applicability of hybrid composites in temperature, chemical, and humid environments. In addition, the tracing of chemical bonds for hybrid composites can be done using Fourier Transform Infrared Spectroscopy (FTIR). The load-bearing capacity and transferability of the hybrid composite were solely based on the bonding of the fiber reinforcement, the filler, and polymer resin.

摘要

强度、重量、刚度、环境友好性和易于制造是当今工程应用中选择材料的关键考虑因素. 在本研究中, 采用手糊法将碱处理的tapsi纤维和微花岗岩填料增强为聚酯基体, 制备了混杂复合材料. Tapsi纤维价格低廉, 供应充足, 所需的纤维量需要用最少的努力来准备. 微细花岗岩粉是花岗岩工业产生的未利用工业废料之一. 通过将tapsi纤维含量保持在20 wt.%的恒定值, 并将聚酯树脂中的微花岗岩粉末含量从0 wt.%改变到20 wt.%, 制备了五种不同的混杂复合材料样品. 对拉伸、弯曲和冲击强度等力学性能进行了评估, 以评估混合复合材料的承载能力. 还进行了FTIR和SEM等表征, 以验证杂化复合材料在温度、化学和潮湿环境中的适用性. 此外, 可以使用傅里叶变换红外光谱(FTIR) 追踪混杂复合材料的化学键. 混杂复合材料的承载能力和可转移性完全基于纤维增强体、填料和聚合物树脂的粘合.
